I assume that under load, there will be a lot of water vapour condensation on the inside making it rather foggy and unpleasing to look at. Also aerating the coolant isn't the best idea in terms of longevity of many coolants since oxidation of the active components will shorten the effective lifetime of coolants. Lastly, personally the sound of trickling water will probably drive me mad.

 

Apart from the negative comments above, suppose its unique.

If your going to make a good sized waterfall effect , perhaps you should consider adding in a fan to blow past falling water, this is a technique to cool water below ambient, though for best results one should use a very large tall tube (bong cooler), but none the less, perhaps it may be worth testing.

ofc the downside would be you will need to keep an eye on water level and top it up overtime as it would be evaporative cooling.

if it wern't so hiumid here on the regular, i may have tried this by now,  the science behind it is solid and interesting.  a lot more maintenance than a closed loop though
